BOTTLE.

Specification of Letters Patent.

' Patented Mar. 4., 1919.

Application filed January 18, 1917. Serial No. 143,113.

To all whom it may concern Be it known that I, CARL G. HILGENBERG, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a new and useful Bottle, of which the following is a specification. This invention relates to bottles or other glass containers utilizing stoppers formed of glass or other hard material.

Heretofore, for certain commercial pur poses, it has been the practice to grind stoppers into the necksof the bottles in which they are to be placed so that the stoppers will fit tightly within the necks, bottles of this character being especially desired in the high class, discriminating perfume trade where expensive perfumes are sold.

It is well known to those thoroughly acquainted with the art that bottles or other containers utilizing cork stoppers or glass stoppers with cork sleeves will be accepted by the public when purchasing inexpensive merchandise such as toilet water, hair tonic, etc., but when expensive perfumes are purchased, it has been found necessary, in order to meet the demands of the trade, to place the perfumes in bottles in which no cork is used.

To meet the requirements of the trade expensive machinery has been devised in order that'stoppers may be ground into the necks of bottles, this operation being objectionable not only because of the expense involved in the purchase and operation of the machinery, but also because of the high wages which must be paid to skilled mechanics known in the trade as grinders.

Aside from the objection to the use of ground stoppers, due to the high cost of production, it is well known that no two stoppers are of the same shape and, conse quently, should a stopper inadvertently be placed in the wrong bottle neck, a tight joint would not be effected and leakage of the contents of the bottle would result. Serious losses are thus often occasionedand, in an effort to avoid such losses, it has been the practice to tie the stoppers to the bottles to which they belong, thereby adding to the cost of the bottles to the consumer.

One of the objects of the invention is to obviate the need of grinding stoppers in bottle necks but, at the same time, to provide means whereby molded glass stoppers can be fitted tightly in bottles without the use of cork or the like, without resulting in the use of an unsightly container which will not be received by the discriminating trade, and which is not only cheaper to produce than the bottles using ground stoppers but is less likely to result in leakage.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combi nation and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the inventio1rherein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred forms of the invention have been.

shown. In said drawings Figure 1 is a section through a portion of va bottle having the present improvements combined therewith,the stopper being shown seated in the bottle neck.

Fig. 2 is a section on line 22 Fig. 1. Fig. 3 is a view similar to Fig. 1 and showing a modified arrangement of sealing means.

Referring to the figures by characters of reference 1 designates a portion of a bottle or other container within the neck portion of which is formed an annular groove 2. In

this groove is seated a ring 8 of lead or other soft material said ring projecting inwardly beyond the inner surface of the-bottle neck so as to be directly engaged by the tapered stopper 4 when inserted into the bottle neck.

expand the soft metal ring and force it ra-.

dially into the groove 2 so as to pack tightly in the groove and at the same time frictionally engage the stopper. Thus leakage past the ring while the stopper is in place will be prevented and the ring will grip the stopper with sufficient friction to prevent the stopper from being inadvertently removed. Consequently, although the stopper and the neck are not ground, the sealing of the bottle is ground. Then too, even though the stopper should not fit accurately within the neck under ordinary conditions, it will shape the" ring-*2 so as to fitsnugl-y therearound-noniat ter what its contour may be, thereby insuring against leakage.

The metal can be of such a color as to cause the neck to have practically thejsame appearance on theoutside as wo'uld'be'" the case should the interior of the neck beprovidd witha ground portion; Likewise should it be desired to' protect the metal froin' 'soi'ne forms of acids itcan beplated with" nickel, silver orthe like'.-

Instead of providing the metal ring withingtheneck'ofthe bottle,itcan be applied directly to the stopper'asshown in Fig: 3. Byreferring to this figure it will be noted thatthe neck of the 'bottleis slightly flared, as indicated at '5 andithat the tapered'stopper 6 has anannular groove 7 in which a ring 8 of lead "orioth'er' soft metal is seated. Thusovhen the stopper is-foree'd into the flaredend of'the bottle neck, this nieta'l'ring will become packed within the groove and will also frictionally'engagethe'wall of the bottleneck, thus adapting itself to the contour' of'saidwall and serving bthtoprevefitleakageand to holdthe stopper tightly in position.

Whfleahe ringihas been described and shown asseat'ed ina groove, it is 'to be under- 'stood'thatif'preferred said ring can engage a ledge projecting inwardly from the bottle necki'orpro'j ecting "out'w ardlv from the stopper, this'ledge being produced by removing the upperwall of the-'grooveshown in Fig; '1

' Or thejlOwi' wall of the groove" shown 'in I Fig:' 3L

What is claimed is ll Thebofnbirfation Wltlf a glass container having a neck portion, of a stopper insertible into said-neekportion and having a tapered portion, one of'sa id portions having an em nular groove, an inert soft inetal ring slidable into position opposite the groove, and meansfor holding the ring in suchposition, said ring being adapted to be pressedinto thegroove"--diiringthe first insertion of the stopper into the neck portion to form a permanent fillin'gifonthe' groove; said ring constituting afriction seal between the stopper and neck;

2.
